NON-REFILLABLE BOTTLE.

To (4Z5 207mm 2'25 may concern:

Be it known that I, FRIEDRICH KUHLns, a citizen of the United States, and a resident of Maywood, Bergen county, New Jersey, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to a non-refillable bottle of novel construction which is devoid of undesirable complexity, constitutes an effective check against spurious refilling, and discharges its liquid contents in a compactly flowing stream. I

In the accompanying drawing, Figure 1 is a vertical longitudinal section of the upper part of a bottle embodying my invention, showing the valve seated; Fig. 2, a top view thereof; Fig. 3, a section similar to Fig. 1, but showing the valve unseated; Fig. 1, a cross-section on line 4: 1 Fig. 1 and Fig. 5, a detail of the valve casing and adjoining parts.

The bottle 10, is provided with a flaring neck 11, which gradually increases in width from its junction with the bottle, toward the head 12. Vithin neck 11, there is accommodated a cylindrical valve casing 13, between the outer face of which and the inner face of neck 11, there is formed a discharge passage 1a, which, owing to the flaring form of the neck, increases in width from its bottom toward its top. At its lower end this passage is entirely closed by a packing ring 15, which closely hugs the valve casing 13, and is accommodated within a recess 16 of neck 11. Within casing 13, there is free to play a ball valve 17 which, in the upright position of the device, settles upon a seat 18, formed by thickening the lower portion of the casing. The upper end of the casing is permanently closed by a plug 19, from which there depends a centrally disposed pin 20, which projects some distance into the casing and constitutes a stop or abutment for the valve, during the tilted position of the bottle. The body of casing 13 is provided with a plurality of longitudinal slots 21, constituting ports, four of such Specification of Letters Patent.

ports being shown. These ports establish communication between the valve casing and the surrounding discharge passage 14, and should extend some distance above the lower end of pin 20 as shown. At some point above ports 21, casing 13 is surrounded by a collar 22, which here narrows the discharge passage 11 to such an extent, that the ball valve 17 is rendered inaccessible to bent wires or other tampering devices.

Vhen the bottle is tilted, the valve will become unseated, so that the liquid is freely discharged into valve casing 13, and thence through slots 21 into the discharge passage 14- (Fig. 3). Should it be attempted to force liquid into the bottle, in this position of the parts, the liquid by entering slots 21 around pin 20, would force the valve upon its seat 18 so that communication between valve casing and bottle is effectively closed. In the righted position of the device, this communication is of course also closed owing to the settling of the valve upon its seat as shown in Fig. 1.

I claim:

A nonrefillable bottle having a neck, a valve casing within the neck and of a diameter to form a discharge passage between said neck and easing, a valve seat at the lower end of the casing, a ball valve engaging said seat, a plug sunk within the valve casing, a pin depending from said plug and constituting a valve-stop, and a plurality of longitudinal slots that are formed in the valve casing and extend continuously upward from the valve seat to points a substantial distance above the lower end of the pin, the upper portions of said slots remaining uncovered during an engagement of the valve with the pin in the inverted position of the bottle, whereby any injected liquid will enter through said uncovered portions and force the valve against its seat.
